Checking charts can be useful, but understanding what caused significant market shifts in the past and calculating how much influence such events have now and in the coming years is also very important.
It is also critical to try to think about what those moves imply, since it is very easy to check the charts and see all the movements that bitcoin made in a matter of seconds, however those movements took months and sometimes a full year to materialize, and living through such movement is a completely different experience than to just look at it on a chart, and anyone that is trying to familiarize themselves with this market needs to remember that soon enough they will have to go through the same experiences, and if they do not go through this process they can be caught with their guard down.
There are a lot of factors that will affect the market movement in the past and in the future but Bitcoin's halving has caused a huge impact on the market.
In the event of the 4-year cycle movement of the market, it gives us an idea of when to buy and when to sell and that is exactly what people are doing now and probably the same thing happen in the future. While people are learning their experience, it also affects the market trends and the stability of the price.
But we don't just focus on the price history of Bitcoin, we also have to take a look at the transaction fees as it also influence the interest of the people. It probably we have some experience in the past but we also expect some changes due to the changing approach of these new investors.
